Hi,
Yesterday we migrated our dev servers to IPA - to help in the migration, I enabled the allow_all HBAC rule, but despite that, some users get this message:
Jul 29 15:56:23 el4966 sshd[98029]: Postponed keyboard-interactive for id094844 from 81.245.6.11 port 35552 ssh2 [preauth] Jul 29 15:56:49 el4966 sshd[98034]: pam_sss(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=el1921.bc user=id094844 Jul 29 15:56:49 el4966 sshd[98034]: pam_sss(sshd:auth): received for user id094844: 6 (Permission denied) < ----- This Jul 29 15:56:52 el4966 sshd[98029]: error: PAM: Authentication failure for id094844 from el1921.bc Jul 29 15:56:52 el4966 sshd[98029]: Failed keyboard-interactive/pam for id094844 from 81.245.6.11 port 35552 ssh2 Jul 29 15:56:58 el4966 sshd[98029]: Postponed keyboard-interactive for id094844 from 81.245.6.11 port 35552 ssh2 [preauth] Jul 29 15:57:00 el4966 sshd[98029]: Connection closed by 81.245.6.11 port 35552 [preauth]
These are external (AD) users. Weird thing: not all users have this and not everywhere... I tried to remove the LDAP filter on the IPA server -> same thing... I'm running out of ideas...
Thanks for your help!

Hi,
please set 'debug_level = 9' to the [domain/...] section in sssd.conf, restart SSSD, try to authenticate again and check krb5_child.log and the domain log for errors.
HTH
bye, Sumit
Thanks for your help!
